In System 78.58, ZMail 38.5, Programmer's Apprentice 21.4, Dungeon 2.1, Detective 2.2, microcode 836, Sorcerer's Apprentice, on Lisp Machine Twenty-two:

c-m-X Extended String Search c-H ? deselects everything
(mode-line => nil).

I tried putting com-extended-string-search on c-S and
decided that it probably wasn't intended for that, since
it had no way (eg) to yank a previous string.  The name
led me to believe that it was a true extension of
com-string-search; and this would seem to be a useful
thing for it to be.  The syntax not being upward
compatible is not important; but it would be a win if the
functionality were.
